> The OpenCSVSerde produces a CSV with all its columns quoted
> no matter of they type or if the string columns contain a separator or not.
>
> The problem is some readers (such postgresql) are not compatible with
> such CSV, in particular when bulk loading them thought COPY statement.
>
> I propose a new CsvSerde, based on a Univocity Parser (wich is used by Apache
> Spark)
> that has been described a 2 times faster thant OpenCSV.
> [https://github.com/uniVocity/csv-parsers-comparison] . This new CsvSerde
> whould only quote columns when needed.
